   > Hi @Kowol, thank you for reporting this issue! This should work and it doesn't - I created a JIRA issue [ARROW-16603](https://issues.apache.org/jira/browse/ARROW-16603) to correct this behaviour.
   > 
   > A (not very nice) workaround could be to go through `pydict` and then back to `pa.Table` again:
   
   Hey
   Thanks for the quick reply :)
   
   This is also something that I figured out yesterday - that I can transform table back and forth to fix the schema. It's not a zero-copy but at least it uses valid schema
